Personally, I try not read a lot when I'm actively writing (which should be WAY more often) so that my voice is distinct while still familiar feeling enough to appeal to my readers.

Having said that, I readily admit to purposefully trying to recreate a certain rhythm and cadence in certain pieces, like the Sons of Conan trilogy, as was deployed by other authors who write in the same genre, including in this case Robert E. Howard, the father of heroic fantasy. That, in my mind at least, is less emulative and more genre specific than say trying to be as horrific and graphic as possible in an effort to be more Kingian, if you will.
